Usage
Near-infrared (NIR) fluorescent probes have become powerful tools for non-invasive monitoring of various biologically important processes in vivo. To meet the requirement of improving the function of NIR, one has to find a material that can render NIR fluorescent probes soluble and selective simultaneously. The hybrid hydrophobin-RGD fusion protein preserving dual abilities can render NIR fluorescent probes soluble and selective simultaneously.
Our team is trying to improve self-assembly and targeting functions from HFBI and RGD peptide and replacing HFBI with BslA.[2]
Biology
RGD is a tripeptide sequence containing arginine-glycine-aspartate, which is a recognition site for the interaction between integrins and their ligands. It mediates the adhesion between cells and extracellular matrix and between cells, and has signal transduction function, thereby mediating many important life activities.[1]
Design Consideration
The construct was cloned into a PET28a plasmid and transformed into BL21 (DE3) E. coli.
The construction includes:
RGD is fused with BslA with a GS linker（GGTGGTGGCGGCAGCGGCGGAGGCGGTAGT）
